Vishay Extends Isolation Capabilities of All SOIC-8 Optocouplers to 4000 V

MALVERN, Pa. — September 21, 2007 — In a move that will broaden target applications for its most compact optocoupler devices, Vishay Intertechnology, Inc. (NYSE: VSH) today announced that all of its optocouplers in the SOIC-8 package have been upgraded to offer 4000-V isolation voltages and 6000-V rated impulse voltages (V_IOTM).

Designed to meet the growing need for higher-rated isolation devices in high-density applications, Vishay offers a wide variety of optocouplers in the SOIC-8 package. The devices include single-and dual-channel devices with phototransistor and photodarlington outputs, as well as high-speed devices up to 10 MBd.

By offering increased isolation and impulse voltages, the devices allow designers to meet higher isolation requirements with a compact device. The SOIC-8 package requires 50 % less board space than the SMD DIP-8, lowering costs and enabling the production of smaller end products. The SOIC-8 package also eliminates through-hole requirements and conforms to standards for surface-mount devices.

Vishay’s SOIC-8 optocouplers are optimized for digital fieldbus isolation, logic and analog signal ground isolation, high-speed D/A and A/D, ATE I/O isolation, and telephone ring-detect applications. Typical end products include PLCs (programmable logic controllers), industrial automation equipment, instrumentation, telecom equipment, and power supplies.
